  • Wilshire Blvd and Tower Drive
  • Wilshire Blvd east of Gale Drive

The equipment to be used during the field testing is described below:

Continuous Core Drilling

Hollow-stem core borings will be drilled using a truck-mounted drilling rig advancing a core barrel into the ground by spinning a 6- to 12-inch diameter casing with a drill bit into the ground to collect samples of the various soil layers. After the exploration is completed, the soil cuttings generated during drilling will be placed in drums, tested for adverse chemicals, and disposed of off-site on a daily basis. The work areas will be scanned for utilities prior to drilling, and the upper soils will be hand augered. At the conclusion of drilling, the hole will be filled with grout and its top patched with asphalt to match the surrounding grade.

What to Expect During Continuous Core Drilling:

  • A drilling crew consisting of up to 4 personnel per rig.
  • A truck-mounted drill rig and support trucks (see photo).
  • Drums to collect soil cuttings for sampling and disposal at conclusion of drilling.
  • Parking lanes and/or up to two lanes of traffic will be blocked while work is underway on business/arterial streets.
  • Moderate noise and moderate vibration.
  • Lanes will be cleared at the end of the work period.

Other Important Information:

  • All work has received necessary permits and approvals.
  • Additional fieldwork following this testing is anticipated. We will inform the area(s) where and when this work will take place.
